convenience

So just like every new owner, I need cupholders. Also in the market for other convenience cool items I may not have thought of...console options? cupholders, storage,..etc please drop your recommendations here for things you bought that make driving that much mo' better. only interior items please

Taking a 10hr drive. Any accessories that would help to make things more comfortable/convenient? Already purchased the BH3D cup holders and air vent phone mount holder. Maybe a seat cushion? Any ideas would be appreciated!
